INFORMATION PROCESSOR AND INFORMATION PROCESSING METHOD, DISPLAY DEVICE, AND PROGRAM

摘要

Disclosed herein is an information processor, including: a receiving section configured to receive an OFDM signal transmitted in accordance with an OFDM system; a FFT arithmetically operating section configured to carry out FFT for a signal within a predetermined interval of the OFDM signal; a delay profile estimating section configured to estimate delay profiles from the OFDM signal received by the receiving section; an inter-symbol interference amount estimating section configured to estimate inter-symbol interference amounts for a plurality of candidates for the predetermined interval, respectively, by using the delay profiles estimated by the delay profile estimating section; and a searching section configured to search for the candidate having the minimum inter-symbol interference amount estimated by the inter-symbol interference amount estimating section from among the plurality of candidates in the predetermined interval, and supply data on the candidate thus searched for as the predetermined interval to the FFT arithmetically operating section.
